maksyuki 4b40dbf262 feat: add CLINT peripheral support and related enhancements 
- Updated the formal file list generator to include CLINT source files.
- Added CLINT timebase to the clock and reset domains configuration.
- Enhanced the SOC topology generation to include CLINT interrupts and their mappings.
- Introduced a new CLINT testbench to validate multi-hart and timebase functionality.
- Modified the software build configuration to define CLINT timebase frequency.
- Updated the RCU module to integrate CLINT timebase generation.
- Adjusted the IRQ configuration to reflect changes in CLINT interrupt signals.
- Added user-visible flags for interrupts in the topology configuration.
- Enhanced the clock reset domain checks to include CLINT timebase.
- Updated the memory map tests to validate CLINT peripheral integration.
